5big2 revive ...

[1oann1s]

Hi all,

I have a 5big2 when at some point, got hit by a lightning strike and the power supply blew up.
I just got my hands on a new power supply and decided to revive the nas running stock lacie firmware and retrieve the data on it.
I am not sure what raid level i had selected during firt intallation...

Powering on:
front led light alternates between blue and red, and rear led lights alternate between blue and red on all bays, and then one by one the red light turns off, blinking only blue
After this process finishes, the rear lights remain off, while the front led light remains static blue.
Although the nas obtains an ip from dhcp I cannot access the web interface.

I have run "fvdw-sl-console" with

UIMAGE-3142-KIRKWOOD-171-standalone

Running "cat /proc/partitions" produces:

I have taken out the disks one by one and attached on a different computer and they all pass SMART.
Only drive on bay 4 reports a few bad sectors.

I would appreciate if you could provide me with any help with tests i can run to emilinate any other hardware issues and retrive data from drives.

[fvdw]

looks like disks are not detected, are they spinning?
Try with only one didk. Your power suply might not be able to startvall the disks

Hi fvdw,

This is the power supply i got. It says that it is a replacement for FSP150-AHAN1. So i expect it to be ok.
https://www.amazon.de/-/en/Chargeur-Adapter-Charger-Replacement-FSP150-AHAN1/dp/B0DHLCZ6H9?nsdOptOutParam=true&sr=8-1

The drives are spinning...

Running "ls -l /dev/sd*" produces the same results even though only the first drive is in the bay...
I was expecting to see only /dev/sda* in results with only the first drive is in the bay...
Also /dev/sdd* is not listed and skipped going from sdc* to sde*, is this normal ?

Is this something to worry about ?

The same is reported by running "nand bad" in the u-boot shell:

What does the following mean exactly ?

[fvdw]

the command ls /dev/sd* is useless it only list sd devices nodes files as present in the directory /dev. Those are always there even if no disks are present in the device.
They are used by the kernel to link a device when it is found.
But as your sata links remains down it means the disks are not dtected. This could be if the sata interface of the 5big2 is defective or the interface board on the harddisk.
The nand bad blocks you can ignore as this flash memory is only used to install lacie firmware on a new empty harddisk. But as long as your harddrives are not coming online that will not be possible
You could chevk your harddisk by connecting to another PC. If it is detected on that PC then your sata interface of 5big2 may be the problem. If the disk is also not detected on the pc then the disk may be dective as result of lighting strike.
Positive is that in the dmesg output you can see that the sata ports are detected an driver is loaded, so mist likely your disks are devective.

Hi again,

Thank you for your assistance up to now. I have also made a donation. Receipt number: 1VV33370K6161862M

I see, so i should check for "cat /proc/partitions" to verify which drives have actually been detected in the system.

I have checked the drives on a separate computer, and they appear to be working.

I took all drives out, and insert them one by one, in reverse order in the bays and reboot each time in standalone kernel shell, ie 5, 45, 345, 2345, 12345, and miraculously, I managed to detect all drives and partitions, sd[a-e][1-10].

So now, how i can mount the raid "md" node from the standalone kernel shell to check the raid configuration and its contents?

What other system or disk tests can i run from standalone kernel, before i try to run the stock firmware again.

Another followup query regarding the nand, if i try to update the stock firmware or flash your firmware, will that write to nand? Will i run into errors due to the bad nand blocks?

[fvdw]

to assemble the array when running the standalone kernel upload the tools using fvdw-sl-programs.
After that

Code: Select all

mdadm --assemble /dev/md4 /dev/sda2 /dev/sdb2/dev/sdc2 /dev/sdd2 /dev/sde2

If this is succesful mount it

Code: Select all

mkdir /md4
mount /dev/md4 /md4

If this is succesfull look in the folder /md4 for content.

If you install our firmware flash memory will not be touched. The data on the harddisk will be lost
